Famous Hollywood director Bryan Singer has been accused in a new federal lawsuit of sexually abusing a 15-year-old boy.

The suit, filed Wednesday in federal court in Hawaii, accused the 48-year-old “X-Men” filmmaker of first preying on the 15-year-old aspiring actor at a party at a California mansion where underage boys were plied with drugs and alcohol and taken advantage of.

“The stories that I’ve heard of what went on at the estate are truly despicable,” the accuser’s lawyer, Miami attorney Jeff Herman, told the Daily News Wednesday night.

Herman identified the accuser as Michael Egan III. Egan, who is now in his 30s and will appear at a Thursday news conference at the Four Seasons Hotel in L.A., was forcibly sodomized by the director when he was 15 in the late-1990s, according to the suit. Singer had promised Egan a role in one of his movies and had numerous sexual encounters with the boy when he was 15 and 16, Herman told The News. Singer also allegedly brought Egan to Hawaii for multiple extended trips when he was 17.

The suit does not specifically demand a monetary figure, but states that the damages suffered warrant in excess of $75,000. In response, Marty Singer, a lawyer for the director, said “it is obvious that this case was filed in an attempt to get publicity,” given that the newest installment of the “X-Men” franchise, “X-Men: Days of Future Past,” hits theaters May 23.
